Murphy’s Law: Why Things Go Wrong at the Worst Time
Have you ever studied all night for a test… only to find out it’s been postponed? Or printed your assignment just before class, and the printer jammed? If so, you’ve already experienced something called Murphy’s Law.
Murphy’s Law is a popular saying that goes:
“Anything that can go wrong, will go wrong.”
It’s not exactly a scientific rule, but it feels true in everyday life — especially when bad timing makes things worse!
The Origins of Murphy’s Law
The term comes from Captain Edward A. Murphy Jr., an American aerospace engineer working on high-speed safety tests in 1949.
He and his team were testing how much sudden deceleration a person could handle (important for pilots and astronauts). But during one experiment, the sensors were wired incorrectly, ruining the results.
Frustrated, Murphy supposedly said:
“If there’s any way to do it wrong, someone will.”
The project leader, Dr. John Paul Stapp, later used the phrase “Murphy’s Law” when speaking to the press. Reporters loved it, and soon the saying became famous worldwide.
Everyday Examples of Murphy’s Law
Here are some times when people might jokingly say, “Well, that’s Murphy’s Law!”
-
You spend hours preparing your presentation — and the projector stops working right when it’s your turn.
-
Wi-Fi is super fast when you’re watching memes, but dies when you're writing an important email..
-
You finally wash your car… and it rains five minutes later.
-
You pick the fastest-looking line at the supermarket - and it turns out to be the slowest one.
Your first flight is on time when you have a long wait for your connecting flight. When you don't have much time between flights, your first flight is delayed.
What We Can Learn from Murphy’s Law
Murphy’s Law might sound depressing, but it actually teaches an important lesson: prepare for the unexpected. Engineers, scientists, and project managers still use it today as a reminder to double-check designs, plan backups, and test everything carefully.
In life, it’s a way to laugh off bad luck and remind ourselves that mistakes and surprises happen to everyone.
Final Thought
Murphy’s Law isn’t really a law of physics — it’s a law of life. When things go wrong, you can get frustrated… or you can shrug and say:
“Well, that’s Murphy’s Law!”
And then you keep going. Because the real secret is not avoiding problems — it’s being ready when they happen.

Hi Graham,
Murphy´s Law is based on entropia´s law, according to which all systems tend to increase the mess. I think it´s the second law of Thermodinamyc. For instance, when I was alone, my room transforms in a mess.
Other examples of Murphy´s Law are:
- Always it rains when you go on holiday. The weather is good on the previous days where you live, but when you arrive to the place when you are going to enjoy your holidays, it begins to rain.
- You buy a sophistificated lamp and when its light bulb goes out you go to shop immediately to buy another, but the employee tells you: “Sorry, we don´t have replacement of this light bulb”.
- Always two socks enter in the washing machine but only one goes out.
- Whe you need to write down something, probably you don´t have a paper and if you have a paper probably you won´t have a pen and if you have both, the most probable will be that the pen doesn´t write.
- When you are on holiday and you are looking for important information, this is on the edge or on the fold of the map.
See you.
I often get a feeling that something is going to go wrong and with the odd exception, I am usually proved right.
I had to consult AI to find out a bit more about entropy. It gives the following definition:
Entropy is a scientific concept that measures the disorder, randomness, or uncertainty within a system, first introduced in physics by Rudolf Clausius to describe thermodynamic processes. It is central to the second law of thermodynamics, which states that the entropy of an isolated system cannot decrease over time, meaning such systems naturally evolve toward states of higher entropy or maximum disorder. You can think of it as the measure of energy spread out in a system, with more spread-out energy indicating higher entropy and a more probable, less ordered state.
Murphy´s Law is based on entropy, according to which all systems tend to increase disorder. I think it´s the second law of Thermodynamics. For instance, even when I am alone, my room transforms into a mess.
Other examples of Murphy´s Law are:
- It always rains when you go on holiday. The weather has been good where you live, but when you arrive at the place where you are going to enjoy your holidays, it begins to rain.
- You buy a sophisticated lamp and when its light bulb blows, you immediately go to the shop to buy another one, but the employee tells you: “Sorry, we don´t have a replacement for this light bulb”.
- Two socks always enter the washing machine but only one comes out.
- When you need to write down something, you probably don't have a paper and if you have a paper you probably won't have a pen and if you have both, the likelihood is that the pen doesn't work.
- When you are on holiday and you are looking for important information, this is on the edge or on the fold of the map. (Don't tell me you still use a map ... even I will use Google maps to find my way around)
